Fungus Causes: Nail fungus (specifically toenail fungus) quickly develops into a serious condition that can spread to other nails. One-in-four people will experience nail fungus in the course of their life and struggle for a cure.

Symptoms: Discoloration and thickening of nails, generally turning yellowish, green, or black and becoming brittle. If left unaddressed, nail fungus can lead to the point of flaking or the nail separating completely from the nail bed.

Treatment Review: Killing nail fungus is a difficult process due to the length of time required to properly treat the condition before seeing results. Fungus grows underneath the nail making it extremely difficult to eliminate. Certain toenail fungus products, like topical ointments, contain nail penetrating ingredients that target fungus underneath the nail bed where the fungus spreads.
